New loss on ignition analyser

Latest Carbolite analyser simplifies and automates asphalt binder content calculations

CARBOLITE’s new ABA 7/35B asphalt binder analyser, which simplifies and automates calculation of the asphalt binder content of hot-mix asphalts (HMAs) used in road surfacing, is optimized for compliance with BS EN 12697-39-2004, ASTM 6307-10 and AASHTO T308-10 standard test methods for determining the asphalt content of HMA using the ignition method.

The ABA 7/35B’s intuitive touch-screen interface is easy to use, even when wearing gloves, with test recipes easily stored, recalled and transferred between furnaces. The system provides automatic collection of weights and correction factors to help reduce errors, while automatic end-point detection and results calculation increase testing speed and accuracy.

Test-specific end-of-test detection methods (percentage or absolute), aggregate correction factors and print outputs can all be selected using the analyser, in order to comply with the standard test methods, while permanent result reports can be printed or output to a USB flash drive.

A central controller takes weight measurements from the internal balance and is able to upload weights from compatible external balances. It also manages temperature control in both the main chamber and the afterburner. During the test process the door is locked while the sample ignites and burns, and then releases with a ‘test finished’ alarm when testing is complete. Logging test results is easy and multiple test methods/recipes can be stored.
